What are the six key elements of host responsibility?

The correct answer highlights the importance of transportation options as part of the six key elements of host responsibility. This element focuses on ensuring that guests have safe transportation alternatives to get home after consuming alcohol, which is vital in preventing intoxicated driving and ensuring the safety of both the guests and the public.

Transportation options can include arranging designated drivers, providing information about public transport, or even providing shuttle services. By addressing this aspect, hosts fulfill their responsibility to promote a safe environment and minimize the risks associated with alcohol consumption.

The other elements, such as food and measures regarding intoxication and underage persons, are also crucial parts of host responsibility, but the focus on transportation emphasizes a direct action that can be taken by hosts to safeguard their guests and the community after an event.
